fumitory family

Habit Plants 1-8 dm. Herbs, annual or perennial, scapose or caulescent, from taproots, bulblets, tubers, or rhizomes; sap clear.

when present leafy, erect to prostrate or climbing, simple or branching.


basal and/or cauline, alternate, mostly compound, sometimes simple, without stipules, petiolate;

blade with 2-6 odd-pinnate orders of leaflets and/or lobes.


, excluding peduncle, 2-3.5 cm;

bracteoles equaling or shorter than pedicels.

terminal, axillary, extra-axillary, or leaf-opposed, unifloral or else multifloral and thyrsoid, paniculate, racemose, or corymbose;

peduncles present;

bracts present.


pedicel rigidly arcuate-recurved in fruit, ca. 3 mm;

corolla 9-14 mm, spur 2-3 mm;

outer petals white;

inner petals white near base, deep red or dark purple apically.

bilaterally symmetric about 1 plane or each of 2 perpendicular planes;

pedicel present;

petals 4, distinct or coherent basally to almost completely connate, in 2 whorls of 2;

outer petals alike or dissimilar, 1 or both sometimes swollen or spurred basally;

inner petals alike, apically connate, clawed, with somewhat hollow, membranous, wrinkled, abaxial median crests;

stamens 6, in 2 bundles of 3 each, opposite outer petals;

filaments of each bundle partially to completely connate, sometimes basally adnate to petals, with basal nectariferous tissue often in form of spur;

anthers connivent, adhering to stigma, median anthers 2-locular, lateral anthers 1-locular;

pistil 1, 2-carpellate;

ovary 1-locular;

placentae parietal;

style threadlike, rigid;

stigma 1, compressed, with 2 lobes or apical horns, and/or 2-8 papillar stigmatic surfaces.


capsular, indehiscent or dehiscent and valvate.

Genera 19, species ca. 450 (4 genera, 23 species in the flora).

The genera of Fumariaceae are distributed mostly in the Old World and primarily in temperate Eurasia. One acaulescent species of Dicentra occurs in Siberia, Kamchatka, and Japan; a caulescent species is found in western China and northern Burma; and nine climbing species are distributed throughout the Himalayan area and Burma. More than 400 taxa of Corydalis and 50 of Fumaria, distributed primarily throughout temperate, often montane, regions of Eurasia and Africa, have been described. Adlumia comprises only two species, which are quite similar morphologically, one from North America and the other from East Asia.

Most European and some American systematists treat Fumariaceae as a subfamily of Papaveraceae. However, although a few taxa are morphologically intermediate, the members of Fumariaceae generally are quite distinct from those of Papaveraceae in several respects, including floral symmetry, sap character, and stamen number and fusion.
